Description

TMR13Dx is an omnipolar magnetic switch integrated

the tunnel magnetoresistance (TMR) magnetic

sensor and CMOS circuitry, which is able to detect

the change of magnetic field and output high and low

voltage signals for high accuracy position detection.

Compared with traditional TMR switches, TMR13Dx

can provide better product performance consistency

by pre-programing the switch points (operating point

BOP, release point BRP, and hysteresis BH) based on

customers’ needs before delivery.

Unlike Hall/AMR sensors, TMR sensors with extremely

high resistance values allows TMR13Dx to achieve

the supply current as low as 1.5 μA while operating in

the full-time power supply mode, and maintaining the

response frequency of the magnetic signal is greater

than 1 kHz. Therefore, TMR13Dx can provide true

continuous detection of magnetic field signals, avoiding

sampling errors from the traditional time-sharing power

supply mode.

TMR13Dx allows a wide range of operating supply

voltages from 1.8 V to 5.5 V with excellent temperature

characteristics, and can meet the requirements of

most applications.
